Air conditioning system
Additional to the heating and
ventilation system, the air
conditioning system has:
AC=cooling4=air recirculationCooling (AC)
Operated with the AC button and
functional only when the engine and
fan are running.
The air conditioning system cools and
dehumidifies (dries) the air when
outside temperature is a little above
the freezing point. Therefore
condensation may form and drip from under the vehicle.
If no cooling or drying is required,
switch the cooling system off to save
fuel.
Air recirculation system 4
Operated with the 4 button.9Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up. The quality
of the passenger compartment air
deteriorates, which may cause the vehicle occupants to feel drowsy.
In warm and very humid ambient air
conditions, the windscreen might mist up from outside when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and avoid the use
of air distribution settings J and V.
Maximum cooling Briefly open the windows so that hot
air can disperse quickly.
■ Cooling AC on.
■ Air recirculation system 4 on.
■ Set air distribution control to M.
■ Set temperature control to coldest level.
■ Set fan speed to highest level.
■ Open all air vents.

86Climate controlRear heating system
The rear passenger compartment
heating fan assists air flow to the rear
passenger compartment via the rear
air vents.
Notice
Country-specific version: Heating
will cease to operate if the vehicle
fuel level drops below 11 litres.
The rate of air flow is determined by
the fan. Air temperature is controlled
using the temperature control on the
instrument panel.
The fan has 3 speeds:
0=off3=high speed
Rear air conditioning
system
The rear air conditioning system is
actuated in conjunction with the front
passenger compartment air
conditioning system.
Rear air conditioning fan switch
The rear air conditioning fan assists
air flow to the rear passenger
compartment via the rear air vents.
Switch on the fan while the air
conditioning system is operating to
allow cooled and dehumidified (dried) air to be distributed.
The rate of air flow is determined by
the fan.
The fan has 3 speeds:
0=off3=high speed

Climate control87Auxiliary heater
Coolant heater The Eberspächer engine-
independent, fuel-powered coolant
heater provides rapid heating of the
engine coolant to enable heating of
the vehicle interior without the engine running.9 Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).
Before starting or programming the
system to start, turn the vehicle's climate control system to heat and the
air distribution to V.
Switch off when not required. Heating stops automatically after the
programmed runtime. It will also
cease to operate if the vehicle fuel
level drops too low.
During operation, power from the
vehicle battery is used. The driving
time should therefore be at least as
long as the heating time. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
To ensure efficient performance,
briefly operate the auxiliary heater
once a month.
Control units
The timer or remote control unit turns the system on and off, and is used to
programme specific departure times.

88Climate control
The control buttons operate
identically to the timer unit described
previously.
To activate the remote control, press
activation button X and release it
when the menu bar appears in the
display. The signal indicator and
SENd appear briefly in the display,
followed by the temperature.9 Warning
When refuelling, switch off the
remote control unit as well as the
heater!
To switch off, press and hold
activation button X to prevent
inadvertent operation.
The remote control has a maximum
range of 600 metres. The range may
be reduced due to environmental
conditions and as the battery
becomes weaker.
In addition to the remote control unit,
the heating can also be switched on
for 30 minutes, or off, using the button
on the instrument panel.
Battery replacement
Replace the battery when the range
of the remote control is reduced or when the battery charge symbol
flashes.
Open the cover using a coin and
replace the battery (CR 2430 or equivalent), ensuring the new battery
is correctly installed with the positive
( < ) side facing the positive terminals.
Replace the cover securely.
Dispose of old batteries in
accordance with environmental
regulations.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.

Teach remote control
If the vehicle battery is reconnected, the LED in the instrument panel
button illuminates and the system
configures the remote control menu
automatically. If the LED flashes,
press OK button on remote control,
select Add or AddE and confirm.
Additional remote control units may
also be configured. Press the button
until LED flashes, switch on the
remote control, select Add and
confirm.
AddE teaches the current remote
control unit exclusively and blocks all
previously configured units. Add
teaches up to 4 remote control units,
but only one unit can operate the
system at any one time.

adjuster wheel left or right.
Direct the flow of air by tilting and
swivelling the slats.
Side air vents
To open or close the side air vents,
turn the adjuster wheel left or right.

92Climate controlServiceFor optimal cooling performance, it is
recommended that the climate control system be checked annually, starting
three years after initial vehicle
registration, including:
■ Functionality and pressure test■ Heating functionality
■ Leakage check
■ Check of drive belts
■ Cleaning of condenser and evaporator drainage
■ Performance check
